Meltdown - S4.E10

As spring arrives and Ray's retirement day approaches, Sean surprises everyone by leaving Buffalo for a job with the competition. So Buffalo brings in Electra pilot Brian Harrison to finish the contract. But as ice strip conditions deteriorate, each flight is riskier than the last. When Buffalo gets the news of former chief pilot Arnie Schreder's passing, Justin flies a DC3 to pick up Arnie's family in Kelowna and brings them back to Yellowknife for a special memorial remembering the aviation legend.
